#29735 [Opn]: Segfault (11) / Possible stack corruption

ID: 29735 User updated by: sparkeh at btinternet dot com Reported By: sparkeh at btinternet dot com Status: Open Bug Type: Reproducible crash Operating System: Linux 2.6.7-gentoo-r9 PHP Version: 5.0.1 New Comment: N.B. Original code tested and works as expected with PHP 4.3.3 Previous Comments: ------------------------------------------------------------------------ [2004-08-18 19:44:13] sparkeh at btinternet dot com There is no loop here. This is segfaulting because the function is failing to return correctly (stack corruption). Remove the "global" statement, and add an echo '' outside of the switch() braces to see normal (expected) program flow. ------------------------------------------------------------------------ [2004-08-18 17:18:38] sparkeh at btinternet dot com What loop?? Remove the "global $moo" and the $rar = 0 and it runs as expected: <? switch($t) { default: function segfault() { echo 'About to segfault : '; } segfault(); } echo 'Or not. Look no loop.'; ?> ------------------------------------------------------------------------ [2004-08-18 17:05:03] derick@php.net ? You call the function segfault() in a never ending loop. ------------------------------------------------------------------------ [2004-08-18 16:17:19] sparkeh at btinternet dot com There is no recursion. This is a function being called from within a switch block. Surely? ------------------------------------------------------------------------ [2004-08-18 15:47:59] derick@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is expected, PHP does not protect against infinite recursion. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
